NETGEAR 8800 User Manual Overview The switch provides full Layer 3, IPv6 unicast routing. It exchanges routing information with other routers on the network using the IPv6 versions of the following protocols: • Routing Information Protocol (RIPng) • Open Shortest Path First (OSPFv3) The switch dynamically builds and maintains a routing table and determines the best path for each of its routes. XCM8800 can provide both IPv4 and IPv6 routing at the same time. Separate routing tables are maintained for the two protocols. Most commands that require you to specify an IP address can now accept either an IPv4 or IPv6 address and act accordingly. Additionally, many of the IP configuration, enabling, and display commands have added tokens for IPv4 and IPv6 to clarify the version required. For simplicity, existing commands affect IPv4 by default and require you to specify IPv6, so configurations from an earlier release will still correctly configure an IPv4 network. ACLs and routing policies also support IPv6. Use of an IPv6 address in a rule entry will automatically use IPv6. Note: IPv6 functionality is supported only on the virtual routers (VRs) VR-Default and VR-Mgmt. VR-Mgmt supports only IPv6 addressing and static routing; VR-Default also supports dynamic routing. The following sections provide additional information on IPv6 unicast routing: • Router Interfaces on page 639 • Tunnels on page 640 • Specifying IPv6 Addresses on page 640 • Neighbor Discovery Protocol on page 642 • Populating the Routing Table on page 643 Router Interfaces The routing software and hardware routes IPv6 traffic between router interfaces. A router interface is either a virtual LAN (VLAN) that has an IP address assigned to it, or, new for IPv6, a Layer 3 tunnel. As you create VLANs and tunnels with IPv6 addresses, you can also choose to route (forward traffic) between them. Both the VLAN switching and IP routing function occur within the switch. Chapter 21.
